Your gut may help your brain decide what to remember

  Pagina openen
Signals traveling from the gut to the brain may help turn meals into lasting memories. Rats showed stronger memory activity after consuming nutritious foods, but not after drinking sweet liquids with little or no nutritional value. Blocking the vagus nerve erased this effect and made it harder for the animals to remember where food had been located. Over time, diets high in fat and sugar also weakened this memory system.

A tiny molecular basket unlocks a powerful new kind of chemistry

  Pagina openen
Rice University chemists have found a new way to make neodymium, a rare-earth metal, interact with oxygen. Using a specially designed molecular structure described as a “basket,” the team positioned the atoms so they could form a bond once thought unlikely. The breakthrough produced highly reactive compounds that could eventually give chemists alternatives to iron-based molecules used in biological reactions and chemical manufacturing.

New Species of Triassic Dinosaur Discovered on Shores of Zimbabwe’s Lake Kariba

  Pagina openen

An international team of paleontologists has identified a new species of early sauropodomorph dinosaur in Zimbabwe, adding to growing evidence that southern Africa hosted a richer diversity of dinosaurs during the Late Triassic epoch than previously recognized.

Hidden Clues in Spirit Rover Data Suggest Mars Once Had Far More Water than Scientists Realized

  Pagina openen

A new look at more than two decades’ worth of archival data from NASA’s Spirit mission suggests that the Martian soil may hold iron-bearing minerals -- hematite and altered magnetite -- that were too faint for scientists to detect in real time during the mission.

Astronomers Spot Wandering Supermassive Black Hole Far From Its Galaxy’s Heart

  Pagina openen

Astronomers have discovered a dormant supermassive black hole 30,000 light-years from the center of WISEA J014656.04-152214.7 -- a massive galaxy located about 750 million light-years away in the constellation of Cetus -- after it briefly lit up by tearing apart a star.

Ancient Footprints in Kenya Hint at Bigger Bodies and Group Behavior among Early Human Relatives

  Pagina openen

A set of 1.43-million-year-old fossil footprints preserved along the margin of an ancient lake in northern Kenya is offering paleoanthropologists new evidence about the size, gait and social lives of the beings who made them and reopening questions about which species they belonged to.

[Editorial] Who owns cardiometabolic disease?

  Pagina openen
A person with obesity, type 2 diabetes, chronic kidney disease, metabolic dysfunction-associated steatotic liver disease, and heart failure might receive five different diagnoses, attend five different clinics, and be managed according to five different guidelines. But these conditions are not independent, they often accumulate along connected pathways shaped by adiposity, insulin resistance, inflammation, and vascular dysfunction. This shared trajectory is increasingly difficult to ignore, as the Lancet Series on cardiometabolic multiple long-term conditions shows.

[Perspectives] Tamzin Cuming: supporting inclusivity in surgery

  Pagina openen
When consultant colorectal surgeon Tamzin Cuming took part in a short film challenging prejudice about women in the workforce back in 2016, she had no idea what the reaction would be. Funded by the UK charity Inspiring the Future, the video showed a group of primary school children being asked to draw a surgeon, firefighter, and pilot—nearly all of them drew men—before the dramatic reveal when Cuming and two other women walked into the room to widespread gasps. It attracted millions of views on social media.

A step closer to artificial organs: UV light shapes arteriole-scale hydrogel vessels

  Pagina openen
The creation of fully artificial organs is a sci-fi dream, and researchers in Japan may have brought it one step closer to reality by developing a new photofabrication technique (i.e., a light-controlled synthetic method) for constructing arteriole-scale tubular hydrogels. Their research is published in the journal Advanced Materials.

Canada's infrastructure projects could damage Pacific salmon habitats

  Pagina openen
The Canadian government is proposing sweeping changes to accelerate industrial development and reduce environmental oversight. These proposed legislative, regulatory and policy reforms could significantly diminish the government's capacity to assess environmental impacts and weaken protections for fish habitats and species at risk.

Stable DNA building blocks enable faster oligonucleotide synthesis without oxidation

  Pagina openen
The chemical synthesis of oligonucleotides (ONs) is central to modern molecular biology, diagnostics and nucleic acid therapeutics. While demand for high-quality ONs is increasing, the conventional synthetic method has long-standing efficiency challenges. Widely adopted P(III)-phosphoramidite-based ON synthesis requires an oxidation step after every nucleotide coupling cycle and uses moisture-sensitive building blocks, adding complexity to the workflow and slowing the process.
